EIGH-SEED ARTICULATED CAR Application filed september 10, 1929. Serial No. 391,638.

This invention relates to `vestibule mountings for articulated cars. An important object of the invention is to provide in a construction of this character an arrangement permitting the vestibule to be held against rotation with relation to the truck and` at the same time permitting the necessary oscillation of this vestibule to accommodate shifting movements of the cars which it connects.

A further object of the invention is the production of a structure of this character which will permit the vestibule to be directly bolted to the truck and held against vertical displacement with relation thereto and at the same time be capable of the necessary oscillatory movements.

i A further object of the invention is the production in a construction of this character of an arrangement whereby the cushioning means for the vestibule, which maintains the vestibule in its normal position and returns vit to such normal position after displacement, may be carried by the platforms of the cars which the -vestibule connects.

A still further object of the invention is the production of apparatus of this character which may be very readily assembled and which will be durable and eicient in service. Y

These and other objects we attain by the construction shown in the accompanying drawings wherein, for the purpose of illustration, we have shown a preferred embodiment of our invention and wherein:

Fig. 1 is a horizontal sectional view through a vestibule mounting constructed in accordance with ourinvention;

Fig'. 2 is a vertical sectional view therethrough on line 2 2 of Fig. 1; and

Fig. 3 is a partially diagrammaticview showing the drum mounting in use between two cars. i

Referring now more particularly to the drawings, the numeral generally designates the truck bolster upon which is seated a car-supporting pivot structure 11 supporting the adjacent ends of cars 12. This supporting structure is substantially identical to that illustrated in the copending application of `Walter S; Adams and Elmer Latshaw for patent on vestibule mountings for high speed articulating cars led August 28, 1929, Serial lilo. 389,004, now Patent No. 1,751,300, granted March 18, 1930, including a supporting plate 13 having an upwardly projecting confinisig rim or retaining flange 141 and a centrally disposed upwardly projecting hubforming flange 15. Between the retaining and hub flanges 1414 and 15 are disposed pivot bloclis 10 having sockets 17 for the reception of socket-engaging elements 18 carried by the car. The upper end of the hub iiange 15 is key-notched as indicated at 19 for the reception of dentations 20 formed upon the lower end of the bolt guide 21 which projects downwardly from a casting 22 rigidly secured to the bottom of vestibule 23 at the axis thereof.

The bolt guide 21 has a bore 22EL for the reception of king bolt 25, the upper end of this bore terminating in a polygonal socket for the reception of the head 26 of the bolt. Beneath the truck bolster the king bolt is surrounded by a spring 27 which acts to prevent vertical displacement of the bolt and, accordingly, to prevent vertical displacement of the vestibule 23 and disengagement of dentations 20 from the notches 19.

The car platforms which are supported from the structure 11 are formed in their upper surface with sockets 28 receiving springs 29 bearing against the under surface of the vestibule floor through wear plates 30. These springs 29 are under compression to support the load of vestibule 23 and any added passenger load and being spaced from the axis of the vestibule will act at all times to maintain the vestibule in its normal position while yielding to permit movement of the vestibule to accommodate relative movements of cars 12. The king bolt-receiving bores of the truclr bolster, casting and hub flange 15 loosely receive the ling bolt so that the upper end of this hub flange operates as a pivot about which the vestibule may rock. A structure of this character permits use of the weather strip tensioning springs 31 at the under surface of the vestibule {ioor as illustrated and described in the copending application above identified.

It will be obvious that with a structure of this character the vestibule will at all times move with the truck and be maintained in a predetermined alignment therewith and thus be maintained in. the best. passible position for alignment with the can bodies.

As the structure employed is obviously Capable 0f a Certain range and Change of rnodilication without materially departing from the spirit of our invention, we do, not wish to be understood as limiting ourselves thereto except as hereinafter, claimed.

We claim:

l. In combination with adjacent ear ends supported from a common truck, a drum vestibule, connections between the drum and truck limiting separation of the drum and truck while permitting oscillation ofv the drum and springs extendingbetween the upper surfaces o said car ends and the` bottom of said drum.

2. In. combination with adjacent car ends, a truck, a bearing element mountedupon the truck including an annular bearing groove and acentr-al hub, bearings for said car ends oscil'latable in the bearing groove, a vestibule drum extending over the` adjacent car ends and lia-vino` at its center a support engaging the hub oii the bearing element, means prevent-ing separation of said support and bearing element and springs extending between thecar ends and the bottom ofthe drum.

3. In combination with adjacent car ends, a. truck, a bearing element mounted upon the truck includingfan annular bearing groove and a central hub, bearings for said car ends oscillatable in the bearinggroove, a vestibule drum extending over the. adjacent car ends and having at its center a support engaging the. hub of the bearing element, and means preventing separation of said support and bearing element and springs extending between the carV ends and thel bottom of the drum, the bearing element and support havengagement with one. another permitting oscillation of the support while preventing rotation thereof.
